The pyrotechnic smoke kit for generating a smoke screen comprises a mixture of a light-metal powder as the metallic reduction agent; potassium nitrate and, optionally, potassium perchlorate as the main oxidation agent; at least one carbonate as an additional auxiliary oxidation agent; substances splitting off nitrogen as combustion moderators and at least one sublimable and/or evaporable non-toxic smoke-forming substance. A stabilizer from the group of aliphatic and/or aromatic dicarboxylic acids is added to the mixture of the smoke kit to stabilize the smoke kit. Due to this, the formation of gaseous ammonia in the smoke kit can be prevented.

Pyrotechnic smoke kit for generating a smoke screen

The invention relates to pyrotechnic primer charges produced on the basis of metal powders or metal hydride powders, potassium perchlorate and binders. In order to obtain a homogenous mixture, the powdery components are mixed with a liquid dispersing agent in a suspension with the aid of ultrasound and dosed having said consistency. Mixing for obtaining a suspension can also be carried out directly in a casing receiving the pyrotechnic primer charges.

Method to produce pyrotechnical igniting mixtures

The invention relates to an electrothermal ignition device for igniting a powder propellant charge ( ), which comprises at least one electrically-conductive wire ( ), that extends, at least partially, through the propellant charge, and can be connected to a current source ( ). The electrically-conductive wire ( ) is coated with a pyrotechnical ignition mixture ( )so that the ignition device can have a low electrical-energy requirement and be easily adapted to the different requirements placed on it. A mixture on a potassium perchlorate-zirconium (KClO &mdash;Zr) base has proven to be an advantageous ignition mixture.

Electrothermal ignition device and method for producing the device

Pyrotechnical mixture for producing a smoke screen

A smoke generating composition consisting essentially of metallic oxide ammonium perchlorate, an organic chlorine donor and a plasticizer and a buffering agent. The metallic oxide includes zinc oxide as one of its components and ammonium perchlorate as well as polychloroisoprene as components of the chlorine donor. All of the components are mixed in such proportions that a neutral fog within the range of pH 5-7 is formed.

Smoke composition

There is disclosed a process for the generation of a dense cloud, as for the purpose of camouflage. Finely divided solid particles are discharged for a container, as by means of compressed gas, the solid particles being in the form of a microfine powder having a particle diameter of up to 60 .mu.m and being impenetrable to visible light and infra-red light of up to 14 .mu.m wave-length and having a settling velocity of up to 5 cm/sec. The powders used are talc, kaolin, calcium carbonates, magnesium carbonates, sodium hydrogen carbonates or other free-flowing powders or powders that have been rendered flowable, which form buoyant clouds upon being dispersed as by atomization.
